Sending this again, since it doesn't seem to have made it to the list:

But that's an interesting point though, the 128 byte alignment issue. Where is
that documented on MSDN ? I.e. it would be good to have a link to the relevant
HD audio spec with regard to the RequestedBufferSize field of
KSRTAUDIO_BUFFER_PROPERTY...
I'm curious though, since I query the buffer for 5292 bytes (6 byte nBlockAlign, 24
bits stereo), I don't see how that'll work, since GCD(5292,128) = 4. How does the
WASAPI KS backend handle this, does it use wBitsPerSample=32 &
wValidBitsPerSample=24 ? Maybe share the WASAPI KS sources ? ;)
TIA
